If you really want the demon to walk around on foot, you can use the standard demon model as a base, adding Agrael's head instead of the standard one, but it will result in a bulky model with a small head – I don't think it will look good. The standard demon is already very awkward – too bulky and the armor is very heavy.
Well, in principle, Agrael's head can be enlarged to fit the bulky body of the standard Inferno unit...

But here, he doesn't look like his artwork(((
Why don't you create something like this:
Because he uses armor in battle, and without it, he's just posing for show for the Inferno girls! :smile47:
